Sexual morph: Saprobic on decayed wood at a mangrove stand. Sexual morph: Ascomata 125–140 μm high, 105–115 μm diam., solitary to scattered, lacking stromatic tissues, deeply immersed, dark brown to black, globose to subglobose, uni-loculate, ostiolate, papillate. Ostioles central, apex composed of brown outer amorphous layer and inner yellow cells of textura porrecta and ostiolar canal filled with periphyses. Peridium up to 2.5 μm wide, thick, a single layer of amorphous fungal tissue fused with the host cells, incorporating occasionally in the host tissues. Paraphyses 2–3.5 μm wide, arising from the base of perithecia, composed of long, wide, filamentous, thin-walled cells, guttulate, unbranched, septate, slightly constricted at septum, narrow towards the apex, with apex blunt. Asci 40–50 × 7.5–10.5 μm (x = 45 × 2.8 μm, n = 20), 8-spored, unitunicate, clavate, long pedicellate, apically rounded, with J- subapical ring, initially deliquescing. Ascospores 7.5–8.5 × 2.5–3 μm (x = 8 × 2.8 μm, n = 30), overlapping bi- to tetra-seriate, allantoid, light brown, aseptate, 1-septate at maturity, not constricted at the septum, smooth-walled with one to few small guttules, slightly curved. Asexual morph: Undetermined.
